Flash Pyrolysis – Synthetic and Mechanistic Aspects
CHIMIA, 1977 Some examples of synthetically useful flash pyrolysis reactions are presented, and the reaction mechanisms are discussed. Cyanocyclopentadienes, -indenes, and -pyrroles are produced by pyrolysis of the appropriate triazoloarenes or isatins, or as the ...

Advanced Functional Materials, EarlyView.The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
